Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a firewall (Linux of course!) to which attaches my cable modem, local internal LAN and my webserver.
I have ports 80, 23, 25, & 110 setup as pinholes from my DMZ to my internal LAN for accessing my webserver. All my websites work correctly within Apache and all is well.
However, I want to setup my webserver box (Redhat 7.3) to receive my mail as well. I have Fetchmail, Postfix, and qpopper installed and want to collect my mail using M$ Outlook.
Outlook connects to my pop3 server (and therefore in theory can collect my mail), but cannot connect to the smtp server (Postfix) and I cannot understand why? In Outlook I use the IP address of the server rather than "localhost". I haven't done much with Postfix as I believe it should work "out of the box" - am I wrong? I've had a look through and there doesn't seem to be much to configure that doens't already look correct (and it IS running before anyone asks!)
Am a bit stumped now, can someone please point me in the right direction??
